Though baffled by the attack as Jaipur was not on the terror radar, sources said the tell-tale signs of the blasts indicate HuJI's hand.
According to these sources, the blasts showed that HuJI, which is being mainly run from Bangladesh, has managed to establish cells in Rajasthan and that the outfit was responsible for previous major terror attacks including the New Year eve attack on CRPF camp in Rampur and serial blasts in three other places in Uttar Pradesh.
The last terror strike in Rajasthan occurred on October 11, 2007 when an explosion in the Dargah of Khwaja Moinuddin Chishti in Ajmer left two persons dead and 17 others injured.
HuJI outfit, suspected to be behind the blast at the sufi shrine, had used a mixture of Tri-Nitro Toluene (TNT) as the explosive material.
